CAR-AXLE-BOX LID.

Specification of Letters Patent.

Application led July 21, 1916. Serial No. 110,536.

To all whom t may concern Be it known that we, DAVID WV. McCoRD and IVAR A. RANDEL, citizensv of the United States, residing at New York and Chicago, respectively, in the counties of New York and Cook, respectively, and States of New York and Illinois, respectively, have invented certain new and useful Improvements in Car-Axle-Box Lids; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.

Our present inventionhas for its object to provide an improved car axle box lid. Particularly, the invention relates to that type of journal box lids disclosed and claimed in Letters Patent No. 803,155, granted to W. G. Dunham, of date, October 31,1905, and entitled Car axle box lids. Car axle box lids of this type are generally designated as center bearing lids, and are provided on their inner faces with projecting spring brackets between which, and an outwardly projecting. portion of the hinge lug of the axle box, thrust springs are compressed. The thrust springs thus applied are held in position by coperating bolts, and are arranged to move from one side to another of a dead center, or neutral position, when the lid is moved from closed to open position, or, conversely, from open to closed positions. Furthermore, the said spring device normally holds the lid closed, but when the lid is opened, exerts a force maintaining its open position, until the spring is overcome by force applied to the lid.

The invention provides an extremely ef cient, yet inexpensive pressed steel or sheet metal lid provided with the required spring bracket for the application of the thrust spring, and with trunnions or bosses for pivotally connecting the lid to the hinge lug of the axle box.

ln the accompanying drawings which illustrate the preferred form of the improved lid, like characters indicate like parts throughout the several views.4 Referring to the drawings:

-Figure 1 isa front elevation of the lid, some parts being sectioned;

Fig. 2 is a section taken approximately on the irregular line m2 :1:2 of Fig. 1, and showing the same applied to an axle box; and

l Figs. 3 and 4 are details in section on the line m4 of Fig. l, the spring bracket being 3. The

hinge trunnions that engage the extremities of the passage 3 of the hinge lug 2. When the lid is to be applied to a hinge lug, simply having the passage 3, the lid should be applied in position and then the bosses 6 should be pressed into the said passage 3. However, it is possible to provide the hinge lu in its sides, with trunnion entrance channe s leading tov the outer extremities of the trunnion seats afforded by the passage 3, and in such arrangement, the bosses or trunnions 6 can be formed before the lid is applied to the box. Hinge lugs with' such entrance channels are, for example, illustrated in the patent to W. C. Reed, No. 1,095,737. When the lid is thus pivotally connected to the hinge lug, it is so mounted that when closed, it'will bear against the mouth of the box.' The hood 5very greatly stitfens the intermediate portion of the lid, but to further stiil'en the outer side portions thereof, it is preferably formed with outwardly pressed corrugations 7.

The spring bracket in the lid is formed as an element distinct from is, after being formed, properly attached to the lid, preferably, by the interlocking engagement shown in the drawings. This spring bracket 8 is formed from a fiat piece or bar of steel or iron bent into approximately L-shape, and one arm thereof is telescoped into a pocket formed on the lid. This pocket is best afforded by cutting'. parallel slits in the .lid and pressing inward that portion 9 that is between the slits, so as to afford the said pocket for the reception of the depending arms of the said spring bracket.

The inwardly projected arm of the spring bracket 8 has a perforation through which is passed a spring retaining bolt 10, the upper end of which is pivoted at 11 to a portion of the hinge lug 2 that is outwardly offset from the passage 3 of said lug. The lid spring 12 is a coiled spring loosely the lid proper and j placed'arour "l the bolt 10 and compressed between the bracket 8 and a flange 13 on said bolt. This improved pressed metal lid .is not only strong, durable and generally therewith. y

3. A pressed metal lid formed with the hood adapted to embrace a hinge lug of an axle box, the sides of the hood having inwardly pressed trunnions affording bosses for engagement with seats in said hinge lug.

4. A pressed sheet metal axle box lid having a hood of less width than its body portion, the said hood extending above the upper edge of the body of said lid and adapted to embrace a hinge lug on an axle box,

the sides of said hood being formed with in-V A ,wardly pressed trunnions affording bosses with parallel slits and having the'portion` for engagement Withsaid trunnion seats. v 5. A pressed metal axle box lid formed in, the other arm of said bracket being projected from said lid and formed with a perforation through which the retaining bolt of a spring device may be passed.

7. A pressed sheet metal lid having a hood adapted to embrace a hinge lug, the' sides .of said hood being formed with inwardly pressed trunnion-forming bosses for engagement with seats in the hinge lug of an axle box, and an independently formed spring bracket attached to said-lid projecting from the inner face thereof and having a perforationthrough which the retaining bolt of a spring' device may be passed.

In testimony whereof lwe aiix our signatures in presence of two witnesses.
